Title: Method for the Production of Patterned Bodies.
IPC: B29C71/02
Filed: 1967-12-12
Abstract: A body made of plastics material which when heated changes colour is provided with a colour pattern by heating selected portions of the body. The bodies may be spectacle frames and bows thereof, and small parts, e.g. buttons made of plastics duroplastic materials including epoxy resins, unsaturated polyester resins or polyurethane resins. The body can be laid on a heat source shaped to the desired pattern (Figs. 5, 6, not shown). Alternatively, the body may be shielded from a heat source by a mask of the desired pattern either placed in contact with the body or maintained at a distance therefrom. The body may be moved relative to the heat carrier and/or the mask. Heating may also be effected by means of heated liquids, e.g. the bodies may be partially immersed into heated vegetable oils, mineral oils, asphalt, silicones, metal baths or polyvalent alcohols, e.g. glycerol. The intensity of colour change is varied by adjusting the heating temperature and/or the heating time. Organic dyestuffs are preferred as the heat sensitive material, particularly translucent dyestuffs, e.g. of the azo-type. Substances may also be compounded with the bodies which under the influence of heat produce oxygen for oxidation and resulant colour change of plastics material. Oxidation is thereby effected in the innermost layers of the bodies. The plastics material may also be compounded with a substance the colour of which is changed by oxidation. In an example a mixture of a polyepoxide, a polyamide, a violet dyestuff compounded to a paste was cured at 100 C. within half an hour. The body was covered by a patterned mask and moved at a distance of 5 centimetres over heating plates heated to 400 C. In Fig. 1 body 5 is fixed to a mask 1 fixed to a conveyer chain 2 arranged to move over a heating element 3. In other embodiments (Fig. 3, not shown) the body is clamped between two masks and a heater is arranged on each side of a section of a conveyer chain. In Fig. 4 (not shown) one heating element is replaced by a reflector.

Title: Sample-and-hold circuit
IPC: H03D13/00
Filed: 1971-04-30
Abstract: A sample-and-hold circuit employs first and second transistors having serially coupled collector-to-emitter current paths and including a negative feedback path coupling the collector of the first transistor to the base of the second transistor to provide a high-input impedance and a relatively low-output impedance circuit suitable for driving, for example, a capacitive load. The detector is keyed by means of a single keying transistor which provides a conduction path from the collector and the base of the first transistor to ground. Diodes coupled in series with the keying transistor and both the base and the collector of the first transistor insure that the first and second transistors are switched in and out of conduction simultaneously. The circuit may be employed as a phase comparator.
Patent ES-401258-A1 (ES)
Title: Arrangement in a hot water-circulating heating system
IPC: F24D19/10
Filed: 1972-03-28
Abstract: A gas burner heats water to be forced through radiators by a pump. A valve assembly on the forward or feed conduit has a connection going to the radiators and a connection going through a by-pass to the return conduit. In the by-pass conduit is a heat exchanger for heating water to be consumed. A temperature sensor on the assembly is exposed to and responsive to the unheated water to be consumed and the heated water in the forward conduit. This temperature sensor operates an electrical switch and, through a lost motion connection, operates the water flow valve in the valve assembly. When this sensor is cool the valve is set to cause the water in the forward conduit to flow through the by-pass and the electrical switch is closed. As the temperature sensor heats up its first opens the electrical switch and thereafter moves the valve to a position at which the heated water in the forward line flows to the radiators. For summer operation the gas burner and the pump are controlled through that switch. For winter operation that switch is by-passed and a room thermostat controls the electric supply to the gas valve and pump. Also included in the electrical circuits are switches responsive to the flow of water to be heated through the heat exchanger and water temperature limit switches.
